Why Choose the Mersen CMS142P Modulostar Fuse Holder?
The Mersen CMS142P, manufacturer item number G331022, is a robust two-pole modular fuse holder prepared for auxiliary microswitch monitoring. Designed for 14 × 51 mm cylindrical fuse-links, it forms part of the Mersen Modulostar CMS14 series for dependable circuit protection in industrial power distribution, machinery and automation systems.
The CMS142P provides two-pole fuse protection in a compact DIN rail mounted assembly. Its microswitch-compatible design allows suitable auxiliary contacts to be added for remote status indication, enabling integration with PLC inputs, alarm circuits and supervisory control systems where rapid fault identification is required.
With a rated current of 50 A, an operating voltage of up to 690 V AC or 690 V DC and a 100 kA short-circuit current rating, the CMS142P is suitable for demanding industrial circuits. Its IP20 finger-safe construction helps protect users from accidental contact with live components, including during fuse replacement when correctly installed.

Reliable Fuse Protection with Remote Monitoring Capability
The Mersen CMS142P provides secure mounting and electrical connection for two cylindrical fuse-links used to protect AC or DC circuits against overloads and short circuits. When fitted with correctly selected 14 × 51 mm fuse-links, it helps prevent excessive current from damaging cables, machinery and connected electrical equipment.
Its provision for auxiliary microswitches allows the fuse-holder status to be communicated to an external alarm, PLC or monitoring system. This can help maintenance teams locate affected circuits more quickly, reduce troubleshooting time and improve equipment availability in automated or continuously operated installations.
Typical Applications
- Industrial control panels and switchboards.
- Motor and transformer protection circuits.
- Automation systems with remote status monitoring.
- Variable speed drives and power conversion equipment.
- Low-voltage electrical distribution systems.
- Industrial machinery and production equipment.
- OEM electrical panel assemblies.
- Commercial and industrial infrastructure.
